Codeanywhere: Setup a WordPress environment from GitHub repo

A quick guide to setting up a WordPress development environment in the Codeanywhere online IDE (https://codeanywhere.com/) and linking to an existing GitHub (or other) source control repository (which I assume also contains the WordPress core code).
It’s not entirely obvious so hopefully this helps.

I’m assuming

You have already created an account a Codeanywhere.

You have already linked Codeanywhere to to your GitHub (or other) source repository.

Step 2: A “Connection Wizard” dialogue will open. Select “GitHub” (or your relevant source) from the left-side list. A list of repositories will be displayed in the dialogue.

Step 3: Select the repository you want to use. Then un-tick the “Autodetect stack” option below the list (this is what I missed the first time – autodetect doesn’t actually work that well).

Step 4: In the next step of the “Connection Wizard” dialogue, scroll down (or search) until you see a “PHP” stack containing “PHP Develppment Stack with Apache, PHP, MySQL, phpMyAdmin and Composer installed”. You can select either Ubuntu or Centos (I work with Ubuntu).
Then select “Create”.

That’s it!

A new LAMP environment connected to your GitHub repository should soon available and showing.

Note: I’m new to Codeanywhere (13 May 2019). I’m switching to this IDE from the soon-to-be-closed-and-fucked-by-AWS Cloud9 (c9.io) as my primary IDE for WordPress and so far I’ve only followed the above steps and managed to work [so far successfully] in the SSH terminal. I’m not yet sure about the lifecycle of the Codeanywhere environments yet, or how to run multiple in the editor.
